I think what you meant to say was that you need to use -1 to use the hz rate you requested, regardless of what the display is doing. I guess the o/s really doesn't provide a hz rate unless you use Flip 1 to sync with it, or you open on the desktop without specifying one. But like you said maybe it's Blitz that's defaulting it to 60 and not the o/s.
I think the best approach is to basically be in control, to know what screen modes are available and to allow only available modes/refresh rates to be used. And the more you can make your engine flexible to adapt the better.
